Map I/O Data
You must map the I/O data to the ControlLogix controller produced/
consumed data blocks and offset locations before you can scan the Remote I/
O network. After mapping is complete, you must export the aliases to the
1756-RIO module and import them to the RSLogix 5000 project.
for a detailed discussion of Exporting/Importing
Aliases.
Unassigned I/O addresses are shown as xxx in the I/O tree.
Automatic Mapping
The configuration tool maps all unassigned I/O to produced/consumed
inputs and outputs. It leaves any previously assigned addresses unchanged.
On the 56RioCfg configuration tool dialog box, from the Map command on
the main menu, choose Automap Any Unassigned to automatically map the
data.
IMPORTANT
If you change mappings, make sure you clear the output table in
the ControlLogix controller to prevent inadvertently writing to
an incorrect I/O location. If you leave a value behind in the
output table, it now points to something else on the Remote I/O
network. To clear the output table, set the outputs to 0.
